WARP-CONTROLLED CONTROLLING MEANS FOR LOOMS.

Appflication filed October 6, 1923. Serial No. 663,901

To all whom it may concern:

Be it known that we, THOMAS HANNEY and JOHN H. BECKER, citizens of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in arp-Controlled Controlling Means for Looms, of which the following is a specification.

In looms having warp-controlled electromagnets to do certain work, as to cause stopping of the loom when a warp-thread breaks or becomes unduly slack, it is necessary to provide at present space for the system of fallers or other controlling devices for the circuit, which thus encumber the loom, and

there is the further disadvantage that the harness cannot be taken from the loom along with the warp (so that the loom can be continned in operation with another harness and warp) because of the engagement of the warp threads with the several controlling devices, which are not conveniently demountable from the loom. Therefore it has been proposed to place the controlling devices in the heddle-frames of the harness,

and it is to this class of warpstop motions in particular to which our invention relates.

The principal object of the invention is to provide a heddle-frame containing the fallers as well as the heddles and having the former kept against tilting forward or back,

when they fall, out of the plane in which they are suspended and so into the way of an adjoining heddle-frame by means entirely below the eyes or equivalent warp-threadengaging portions of the fallers, so that the upper ends of the fallers are unguided and free. This construction makes possible a very material reduction ofthe weight that is added to the heddle-frame when the fallers are arranged therein, for the fallers need only be of such length as to extend upwardly approximately to the middle (measurer vertically) of the heddle-frame. Our invention further contemplates constructing the parts of the improved mechanism which are to be carried by the heddle-frame so that they will be inexpensive to manufacture and capable of ready application to heddle frames in common use.

In the accompanaying drawings, Fig. 1 is a front elevation of a common form of heddle-frame equipped with the parts constituting this invention in one form thereof;

Figs. 2 and 8 are sectional views on the line 2-2, Fig. 1, illustrating the two different positions of a taller;

Fig. 4 is a horizontal sectional view through "the trough forming member 1;

Fig. 5 shows a faller in front and side elevation; V

Fig. 6 shows a fragment of the heddleframe equipped with the parts constituting our invention in another form thereof; and

Fig. 7 is a sectional view on line 77, Fig. 6.

l The heddles-frame shown comprises the usual top and bottom rails a 7), the metal side or end bars 0 connecting theends of these rails; the top and bottom bars (Z c on which the heddles f having eyes f, are strung, these bars being kept taut by the usual spring clips g, and the top and bottom rods h e' which are mounted in eyes i driven into the rails and carry hooks 7a which engage the heddle-bars d e at intervals to re inforce them against the strain of the warp as the frame reciprocates vertically.

Referring, first, to Figs. 1 to 5: In the lower part of the heddleframe, to wit, just above the bar 6. and in plane to one side of that of the heddles f is arranged a horizontal strip Z forming a trough Z in which at the bottom thereof, is arranged a pair of spaced terminal bars 911. extending lengthwise of the trough and insulated from each other. The terminal. bars may be and in this construction preferably are insulated from each other by forming the strip Z of insulating material and setting them in the same. The ends of the strip abut the inner faces of the side or end bars 0 of the frame and may be rigidly secured thereto by screws n or otherwise. One end of said strip may have a. projection Z which extends through a hole in the corresponding side or end bar and through which project the ends of the terminal bars, which are equipped with bind ing posts or equivalent means 0 for attaching thereto the ends of the conductor 2) of a circuit including a source of energy p and an electro-magnet p whose armature 79 forms the element to be actuated when the breaking or slackening of a'thread A occurs. Above the strip Z and made to connect the side or end bars 0 in any way in a horizontal bar 9. Both the strip Z and this bar, it will be noted, are below the horizontal plane of the warp-guiding portions or eyes f of the heddles. Each faller ris a strip of metal hav ing an eye r at one end for the reception of a warp thread and at the other end a contact nub 1 which is preferably a rounded projection extending from one face of the strip, being rounded around a horizontal axis parallel with the plane of the strip; between its ends, but nearer the end having the nub 7*, a slot r is formed by slitting the strip longitudinally and then bending the metal both sides of the slit in opposite directions out of the main plane of the strip. Each faller is arranged in the heddle-frame as shown best in Figs. 2 and 3, to wit. so that the bar 9 penetrates its slot r and its lower' end is received in the channel or trough of strip Z. When the heddles are to be threaded with the warp threads A each'fa-ller is raised so that its eye 7" registers with the eye f of the corresponding heddle and both eyes are threaded at once. hen the loom is operating the tension of the warp of course maintains all the fallers elevated as in F 2 so long as none of the warp threads breaks or becomes unduly slack; in either of these eventualities the'faller afiected will fall and its nub 1" will contact with the bars m, closing the circuit. The nub is rounded in the specific way described so that in crosssection thereof in avertical plane transverse of the portions forming the sides of the trough it has the same thickness; thus, since it is nearly as thick as the channel of the trough is wide, it serves to keep the faller from assuming a skewed position or always faced substantially as shown in Fig. 1.

In Figs. 6 and 7 the channel or trough for the lower ends of the fall'ers is formed in the lower rail of the heddle frame, the construc tion of the entire structure being the same. except in the particulars now to be indicated,

as that already described. This rail has a rabbet 8 formed in one vertical face thereof at the top and extending nearly to each end thereof and this is covered by an elongated strip t which may be secured to the rail by screws a and has a rib t at the inside which rests on the bottom surface of the rabbet and in which is set the pair of terminal bars o. These terminal bars are equipped with the binding posts to for the circuit conductor p, and the end of one is bent up and over the other as shown in Fig. 6 so as'to bring both binding posts as near as possible in the same vertical plane, said ends being set in insulation a; where they penetrate the side or end bars 0. The strip t, as well as the rail 6 (which is of wood), are insulative.

In both constructions the weight which is added by incorporating the fallers in the heddle-frame is reduced approximately one-half by arranging the means which keeps the fallers against tilting forward or backward when they fall (to wit, bar q and the trough) below the eyes r of the fallers. The nubs r on the fallers, by desirably weighting them at their lower ends and by being rounded, in sure certain contact of the fallers with the terminal bars.
